Book Description
In the past decade, animal scientists have learned that administering recombinantly derived somatotropin (growth hormone) to cows improves milk production and that giving beta-adrenergic agonists to meat animals improves productivity and leanness. In order for these metabolic modifiers to yield benefits, however, sound management of the animals' nutrition is necessary. This volume reports on how these substances work in the animals' metabolism, what effects they might have on nutrient requirements of domestic livestock, and what information should be developed further by investigators. The book explores the current understanding of the biology, structure, mechanisms of action, and treatment effects of somatotropin, beta-adrenergic agonists, and anabolic steroids. A companion volume to the Nutrient Requirements of Domestic Animals series, this authoritative volume will be required reading for animal scientists, researchers, veterinarians, livestock farmers, and faculty and students in university animal veterinary science programs.
Feed efficiency in swine
Author: John F. PatiencePublisher: Springer Science & Business Media
ISBN: 9086867561
Category : Science
Languages : en
Pages : 264
Book Description
'Feed efficiency in swine' has been prepared as a comprehensive treatise on the current state of our understanding of this topic which is so important to the pork industry. Each chapter is written by international authorities who understand both the science and application of their topic area. The book provides detailed insight into the many factors affecting feed efficiency, ranging from diet processing to herd health, from nutrition to physiology and from day-to-day barn management to the adoption of advanced technologies. The authors explain such practical aspects as the challenge of interpreting feed efficiency information obtained on farm or the role of liquid feeding. The authors also delve into more scientific topics such as amino acid or energy metabolism or animal physiology. This book is written for people who have a technical interest in pork production, including nutritionists, geneticists, farm management specialists, veterinarians, other academics and, of course, pork producers.

Book Description
Producers are becoming more aware of product quality as a profit driver in the pork industry. One alternative method is the use of hoop buildings, which are deep-bedded, open-ended, tent-like structures covered with a polyethylene fabric tarp. Several items differ between hoop structures and standard confinement systems, including the use of straw for bedding, increased space allocation, and subjection of animals to seasonal environmental changes. The open-ended design of hoop structures allows greater exposure to temperature changes, with less capacity to maintain a constant temperature as outdoor temperatures fluctuate. The following experiments were designed to ascertain affects between hoop systems to confinement systems. The general hypothesis driving this study was that enrichment of the finishing environment provided by semi-outdoor, deep-bedded finishing systems would allow for lower stress susceptibility, thereby influencing growth response, carcass composition, the rate and extent of pH and temperature decline postmortem, ultimately affecting pork quality attributes perceived by the consumer. Space allocation rates from this study will grant producers using these systems with a standard stocking requirement to efficiently optimize swine growth and pork quality. Hoop-finished pigs were slower growing, with relation to average daily gain and feed conversion capacity than confinement-finished pigs. Hoop pigs also had lower levels of backfat at the 10th rib, less marbling in the loin, and less total lipid in the adipose tissue. The ultimate driver hypothesized for these variations was exposure to ambient temperature fluctuations. Providing more space within hoop systems had small affects on growth, performance, or pork quality attributes. Variations in pork quality were limited to lipid deposition, indicating finishing systems observed in these experiments did not alter product quality. Future research initiatives are necessary to determine specific effects of temperature fluctuation and lipid deposition characteristics in these systems.

Book Description
Swine Nutrition is a comprehensive text-reference that deals with the various aspects and knowledge in swine nutrition. The book is basically about nutrient utilization by swine. The topics discussed concerning this subject are factors influencing swine nutrition, nutrient bioavailability, appetite and feeding behavior, physical forms of feed, environment and management, immunocompetence, genetic and sex considerations, mycotoxins, and intestinal microbiology. Major and unique feedstuffs, feeding regimen in different stages of growth, and techniques in swine nutrition research are also elaborated. The text will be useful to students of advance swine nutrition courses as well as those seeking information in swine nutrition.
